Impact of long-term fasting on the stomach-hypothalamus appetite regulating genes in Atlantic salmon postsmolts
(Peer reviewed; Journal article, 2023)Atlantic salmon will experience periods of fasting during its lifecycle. In nature, prolonged fasting periods occur owing to seasonal fluctuations in available feeds, migration or in relation to reproduction. In a culture ... -
Impact of multiple stressors on sea bed fauna in a warming Arctic
(Journal article; Peer reviewed, 2019)The Arctic Barents Sea is experiencing a record temperature increase, a poleward shift in the distributions of commercial fish stocks, and invasion by the snow crab, a new predator. To evaluate benthic community vulnerability ... -
Impact of ocean acidification and high solar radiation on productivity and species composition of a late summer phytoplankton community of the coastal Western Antarctic Peninsula
(Journal article; Peer reviewed, 2019)The Western Antarctic Peninsula (WAP), one of the most productive regions of the Southern Ocean, is currently undergoing rapid environmental changes such as ocean acidification (OA) and increased daily irradiances from ... -
Impact of sea-ice processes on the carbonate system and ocean acidification at the ice-water interface of the Amundsen Gulf, Arctic Ocean
(Journal article; Peer reviewed, 2013-12-18)From sea-ice formation in November 2007 to onset of ice melt in May 2008, we studied the carbonate system in first-year Arctic sea ice, focusing on the impact of calcium-carbonate (CaCO3) saturation states of aragonite ... -
The impact of seawater warming on fatty acid composition and nutritional quality indices of Trematomus bernacchii from the Antarctic region
(Peer reviewed; Journal article, 2021)There is a growing interest in exploiting Antarctic fisheries for human consumption. However, information on how the nutritional qualities of these resources will respond to the predicted seawater warming in the region for ... -
Impact of solar ultraviolet radiation on hatching of a marine copepod, Calanus finmarchicus
(Journal article; Peer reviewed, 2000-02-28)The calanold copepod Calanus finmarchicus 1s a key component of the zooplankton community in the estuary and Gulf of St. Lawrence, Canada. During the spring and summer months, C. firmarchicus eggs are released into the ... -
The impact of surface currents on the wave climate in narrow fjords
(Peer reviewed; Journal article, 2021)This study investigates the effect of surface currents on wind-generated waves in a complex coastal system with narrow fjords. The simulations are based on a phase-averaged wave model forced with surface currents from a ... -
Impact of thermoclines on the vertical distribution of salmon lice larvae
(Peer reviewed; Journal article, 2020)Salmon louse Lepeophtheirus salmonis, a key parasite of salmonids, is managed by multiple methods at both salmon farm- and ecosystem-scale that are informed by an understanding of the abundance and distribution of the ... -
Impact of ultraviolet radiation on marine crustacean zooplankton and ichthyoplankton: a synthesis of results from the estuary and Gulf of St. Lawrence, Canada
(Journal article; Peer reviewed, 2000-06-26)The objectives of the research program reported upon here were (1) to measure ambient levels of UV radiation and determine whichvariables most strongly affected its attenuation in the waters of the estuary and Gulf of St. ... -
Impact of variable physical conditions and future increased aquaculture production on lice infestation pressure and its sustainability in Norway
(Peer reviewed; Journal article, 2020)Salmon lice infestation is a challenge for wild post-smolt salmon during migration from their natal river to the sea in several regions of Norway. The traffic-light management system regulates growth in the aquaculture ... -

(Peer reviewed; Journal article, 2020)Salmon lice infestation is a challenge for wild post-smolt salmon during migration from their natal river to the sea in several regions of Norway. The traffic-light management system regulates growth in the aquaculture ... -
Impacts of a Changing Ecosystem on the Feeding and Feeding Conditions for Atlantic Salmon During the First Months at Sea
(Peer reviewed; Journal article, 2022)During the last decades, many wild Atlantic salmon populations have declined dramatically. One hypothesis for an observed reduction in salmon marine growth and survival is reduced abundance of prey. However, the effect of ... -
Impacts of bottom trawling and litter on the seabed in Norwegian waters
(Journal article; Peer reviewed, 2018)Bottom trawling and seabed littering are two serious threats to seabed integrity. We present an overview of the distribution of seabed litter and bottom trawling in Norwegian waters (the Norwegian Sea and the southern ... -
The impacts of different management strategies and environmental forcing in ecological communities
(Journal article; Peer reviewed, 2006-07-05)Understanding the effects of population management on the community a target species belongs to is of key importance for successful management. It is known that the removal or extinction of a single species in a community ... -
